# Reference Architecture

The reference architecture for ZoneControl consists of one or more webservers running ZoneControl, fronted by a Load-Balancer. These ZoneControl-instances use one shared database for their configuration and communicate with the API of one or more PowerDNS Authoritative Servers.

## Ports and communications

ZoneControl runs through its built-in gunicorn webserver and it should be put behind another webserver like nginx. See Fronting with nginx
